Disparity in Availability of Laboratory Testing for Syphilis Among Different Hospitals in Shandong Province, Eastern China

Abstract

The aim of this study was to understand the availability of laboratory testing for syphilis among hospitals in Shandong province. Basic information on hospitals that provide clinical health service for sexually transmitted infections (STIs) and the type of laboratory tests for syphilis provided was collected and analyzed using the chi-square test. A total of 410 and 456 hospitals that provided clinical services for STI were surveyed in 2012 and 2018. Significant differences in the availability of nontreponemal tests were observed among different levels (χ2 = 6.624) and types (χ2 = 17.752) of hospitals in 2012, but not in 2018. A significant difference in the availability of treponemal tests was observed among different levels of hospitals in 2012 (χ2 = 9.937) but not in 2018. Significant differences in the availability of nontreponemal tests, titer of nontreponemal tests, and treponemal tests were observed among hospitals with different affiliations in 2018 ( P = 0.000; χ2 = 15.274, P < .001; P = .021) but not in 2012. The availability of nontreponemal and treponemal tests for syphilis among hospitals in 2018 was higher than that in 2012 (90.13% vs. 57.56%, χ2 = 121.219). The availability of laboratory testing has been much improved. Further efforts are needed to reduce the disparity in the availability among different hospitals.
